With the release of Java ME Embedded 8.1 in Nov 2014 we introduced support for ARM Cortex-M based using Freescale FRDM-K64F.

Today, we are extending the Cortex-M support to the STMicroelectronics STM32429I-EVAL developer evaluation board. The STM32F429I-EVAL represents the very popular STM32F4xx MCU family which is being used in a wide range of embedded applications and markets today and is a perfect target for Java ME 8.

What is in the release?

This Developer Preview release brings the power and flexibility of Oracle Java ME Embedded 8.1 to STM32F4xx micro-controllers:

Out-of-the-box support for a rich set of Java ME Embedded 8.1 functionality and APIs

Key functionality and protocol support for networking, serial, storage, file, and peripheral I/O

Note that this release is a Developer Preview for development and evaluation purposes, which means that it has undergone extensive testing but is expected to still have limitations and shortcomings compared to a full product-quality General Availability release.

MicroDoc and Oracle will be doing a joint webcast today on the topic of Java in the Connected Car. Join us to learn about the challenges of connecting vehicles and mobile services, how Java is designed to meet these challenges, and how MicroDoc can help deploying solutions.

While many in the industry are talking about the future of connected cars, Java ME Embedded 8 is rapidly becoming a leading connected vehicle software platform starting to ship in millions of vehicles this year. Join my talk to learn more. For more information on the program, see here.

If you haven’t watched a talk on language stewardship and evolution in a while – I would highly recommend this one.

Brian Goetz, Oracle’s Java Language Architect, makes a brilliant, witty, and passionate case for pragmatic evolution of programming languages and provides compelling reasons why Java not only remains relevant as the top programming language and platform of choice but – even after 20 years – continues to deliver innovation that matters to the entire IT software ecosystem, including 9 million Java developers and those building software with alternate languages on top of the Java runtime.

At JavaOne a few weeks ago, Oracle made available the Java ME 8.1 Developer Preview release for the Freescale FRDM-K64F (“Java ME 8.1 in 190 KB RAM”) and announced the upcoming full release of Java ME Embedded 8.1 (press release).

On Monday this week, we followed up as promised and posted the General Availability (GA) releases of Oracle Java ME 8.1 and the Oracle ME SDK 8.1.

Oracle Java ME Embedded 8.1 and ME SDK 8.1 New Features and Enhancements

With this release, Java ME 8 now fully lives up to its design promise of delivering a feature-rich Java 8 platform that scales from powerful embedded systems all the way down to resource-constrained singe-chip micro-controllers with as little as 128 KB of RAM.

Developers can now rely on a consistent, standards-based programming model and platform that allows true code reuse from large to small solutions … in most cases the same, unmodified application binary will run across the entire range of target devices – irrespective of the underlying hardware and software differences. This means faster time-to-market, improved security and flexibility, and the ability to deliver more product value, faster.

No other embedded software technology can do that today.
